I finally installed my 1st TI Jazz flats last month (bought them in April for my LEJ ) on my newest acquisition, a Korean E7 Squier Bullet I ran across in my local pawn shop that had a frayed E string. Loving the bass and the TIs.
2 things had kept me away-price and concern of being too loose/floppy tension. I've found this not to be an issue ; to me , and am loving everything about these strings. A lighter touch is rewarded. I've noticed a little clang and fret noise if playing aggressively but not coming through the amp.
Seriously thinking of restringing all my roundwound basses with these. I have a bunch strung with other flats, tapes and one with pressure wounds-probably leave those as is .
The Matt Freeman is a great bass , I think well suited for the TIs. My buddy has one and the stock pickup isn't bad at all but the Duncan is a great choice for a not too hot vintage voiced replacement.
Haven't tried the Pyramid Gold Flats but have wanted to as well. Rumors of not like they used to be, uneven string to string output , unraveling, too dead E against the other strings -I'll find out one day myself.
